Martinez guarantee's KO against Murray

The fight will be the first for Martinez in his native Argentina in over 11 years, and first ever since becoming a middleweight champion. The championship bout will take place at the country's famed 50,000-seat Club Atletico Velez Sarsfield in Buenos Aires, Distrito Federal, Argentina.

Martinez is not only the world's pre-eminent middleweight but is also regarded as one of the planet's finest pound for pound.

Murray won't be able to beat the 38-year-old Martinez by running around on the outside like his fellow countrymen Darren Barker and Matthew Macklin tried to do to beat Martinez. It was a total failure with Martinez stopping both of them. Those two fighters wasted any chance they had of winning the fight by fighting defensively instead of making Martinez work hard by pressuring him to show his aging skills.

Those two fighters had an advantage the 30-year-old Murray doesn't have and that's in the power department. Murray can pressure Martinez but without power, he's going to be in a lot of pain. That doesn't mean that Murray can't win. It's possible he could wear Martinez down and earn a decision but it's just unlikely.

Murray will have to eat a ton of hard punches for him to wear Martinez down, and I just can't see Murray being able to take those heavy shots without going down or getting punished badly enough to where he'll have to go into survival mode in order to end the fight in a standing position.

Martinez said "There is no doubt in my mind that this fight is going to end by knockout. My training for this fight has been the best I have ever had and my confidence is at the absolute highest level, and for that reason I guarantee this fight will end in a knockout on Saturday night."

Murray responded, saying "Sergio is a great fighter, and I have nothing but the utmost respect for him. All that being said though, I didn't come here to lose. I have had a great training camp and I feel that this is my time. Whatever Sergio brings on Saturday night I will be ready for it."

Boxing's answer to 'goal-line' technology will be used in this bout.

'Instant Replay' from HBO footage will be used in the event of any controversies over cuts and fouls to ensure fair play.

WBC secretary General Mauricio Sulaiman said "Boxing needs to move into the 21st century and use the technology we have available to us, to make sure justice prevails in this sport. Justice is not served in our sport when fouls or accidental actions occur, creating unjust results."

If it proves successful, 'Instant Replay' could eventually be used in all major title fights.
